I don't know about yours but I installed my rear suspension a few days ago and I am not that impressed. When I pick the truck up there is nothing to keep the axles and springs from moving all over. The axles drop a bunch and the springs rock around. They need to have mounts on top of the spring pads to keep everything in place like a real truck(I will be making myself some). Also when using this style front tandem axle with stock Tamiya X members and KH spacing there is almost no upward travel. Kinda bummed with mine from a mechanical standpoint...

Yours is looking very nice though and I am looking forward to the next update!
